Nest Attendance and Reproductive Success in the Wood Thrush
Bibliographic record
Abstract
For most bird species, biparental care is expected to play an integral role in offspring survival. Nevertheless, relatively few studies have simultaneously examined male and female investment into nest attendance, the prevalence of nest attendance through the nesting cycle, or the relationship between nest-attendance effort and nesting success. Here, in a monogamous passerine, the Wood Thrush (Hylocichla mustelina), we use radiotracking to examine nest-attendance behaviors of males and females during the laying, incubation, and nestling stages, and the relationships between nest attendance and nesting success. Across nesting stages, males spent between 14–38% of their time <5 m and 21–58% of their time 5–25 m from the nest, and the time males spent near the nest was positively associated with nesting success. During the incubation stage, the amount of time males spent <5 m from the nest depended upon the female's presence on or off of the nest, as males appear to coordinate their nestattendance behaviors with females. Overall, our results indicate that male Wood Thrushes invest extensively into indirect parental-care behaviors throughout the nesting cycle and that increased nest attendance translates into improved offspring survival.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
